Description

Die Erfindung . betrifft . die Einzelabfederung der beiden lenkbaren, mit Bremsen versehenen Vorderräder von Straßenfahrzeugen mittels übereinander angeordneter Blattfedern. Bei gebremsten Rädern muß das von den Bremsen ausgehende Drehmoment auf den Wagenkasten bzw. das Fahrgestell übertragen werden. Sind die Räder an Lenkern gelagert, so bestehen hier keine Schwierigkeiten; werden zum Abfedern der Räder aber Blattfedern verwendet, so ist zu be- * achten, daß solche Federn nicht auf Verdrehung beansprucht werden sollen. Dies ist aber der Fall, wenn die Federn am Wagen quer angeordnet sind. <The invention . regards . the individual suspension of the two steerable, with brakes provided front wheels of road vehicles by means of leaf springs arranged one above the other. When the wheels are braked, the torque from the brakes must on the car body or the chassis be transmitted. If the wheels are mounted on handlebars, there are no problems here; however, if leaf springs are used to cushion the wheels, the * ensure that such springs are not subject to torsion stress. This is but the case when the springs are arranged transversely on the carriage. <

Die Erfindung besteht nun darin, daß an den Enden eines vorderen, gegebenenfalls die, Stoßstange tragenden Querträgers des Fahrgestells in an sich bekannter Weise je, zwei schräg nach hinten und außen ragende viertelelliptische Federn übereinander befestigt sind, deren Enden durch die die Achsschenkel und die damit verbünder.en Bremsbacken tragenden Lenkzapfen der Vorderräder verbunden sind.The invention consists in that at the ends of a front, optionally the bumper-carrying cross member of the chassis in a manner known per se each, two quarter-elliptical feathers protruding obliquely backwards and outwards, one on top of the other are attached, the ends of which by the steering knuckle and the verbünder.en with it Brake shoes bearing steering pins of the front wheels are connected.

Dadurch werden folgende Vorteile erzielt: i. Werden die Vorderräder -abgebremst,-so übertragen ihre Bremstrommeln ein starkes Drehmoment auf den um den Lenkzapfen schwenkbaren Achsschenkel. Liegen die Federn quer zur Fahrtrichtung, so werden · sie durch dieses Drehmoment in einer sehr ungünstigen Weise auf Verdrehung bean-This has the following advantages: i. If the front wheels are braked, -so their brake drums transmit a strong torque to the one around the steering pin swiveling stub axles.

However, are the springs facing the direction of travel inclined at an acute angle, this torque essentially only generates compressive and tensile stresses in the springs. 2. An den Enden des, Querträgers kann bequem die Stoßstange angeordnet werden. In der Zeichnung· ist ein Ausführungsbeispiel der Erfindung schematisch veranschaulicht, und zwar zeigt2. The bumper can be conveniently placed at the ends of the cross member.

Der Mittelrohrträger 1 des · Fahrgestells ist mit einem vorderen Querträger 2 verbunden, an dessen Enden je zwei vier telellip tische Blattfedern 3 angebracht sind.

Die äußeren Enden der übereinanderliegenden Federn 3 sind durch Zapfen 4 verbunden.) um die die Achsschenkel 5 der Räder schwenkbar sind. Diese Achsschenkel tragen Bremsbacken, die im Innern der am Rad befestigten Bremstrommel 8 angeordnet sind. Bremst man die Vorderräder ab, so suchen die umlaufenden Bremstrommeln S die Achsschenkel 5 mitzunehmen. Infolgedessen wird auf die Federn 3 eine Beanspruchung ausgeübt, die im wesentlichen in einer Druckbeanspruchung der oberen und Zugbeanspruchung der unteren Feder besteht.The central tube support 1 of the chassis is connected to a front crossmember 2, at each end of which two four telellip table leaf springs 3 are attached. The ends of these springs are each inserted 1 into a shoe 7 fastened to the carrier 2 and fastened therein. The outer ends of the springs 3 lying one above the other are connected by pins 4.) About which the steering knuckles 5 of the wheels can be pivoted. These steering knuckles carry brake shoes which are arranged inside the brake drum 8 attached to the wheel. If the front wheels are braked, the rotating brake drums S seek to take the stub axles 5 with them. As a result, a stress is exerted on the springs 3 which essentially consists of a compressive stress on the upper spring and a tensile stress on the lower spring. Der Querträger 2 trägt zweckmäßig die· Stoßstange 6 des Fahrzeugs, und zwar unter Zwischenschaltung von federnden Bügeln 9. Die Bahnen, längs deren die Achsschenkel 5 gegenüber dem Fahrgestell 1, 2 geführt sind, sind annähernd Kreisbögen, die in einer durch die Schuhe 7 verlaufenden senkrechten Ebene liegen. Da diese Ebene mit dem Längsmittelrohr 1 einen spitzen Winkel einschließt, vergrößert sich der Abstand der Achsschenkel von der senkrechten Längs- 4! mittelbene des Fahrzeugs, wenn die Räder nach oben durchfedern. Das bedeutet aber, daß das Momentanzentrum höher liegt, als es bei Parallelführung der Räder zu dieser Ebene der Fall wäre. 5<The cross member 2 expediently supports the bumper 6 of the vehicle, specifically below Interposition of resilient brackets 9. The tracks along which the stub axles 5 are guided with respect to the chassis 1, 2 are approximately arcs of a circle, which in a vertical plane running through the shoes 7. Since this level with the longitudinal center tube 1 encloses an acute angle, the distance increases Steering knuckle from the vertical longitudinal 4! central plane of the vehicle when the wheels spring through upwards. But that means that the moment center is higher than it would be the case with parallel guidance of the wheels to this plane. 5 < Patentax-spruch :Patentax claim: Einzelabfederung der beiden lenkbaren, mit Bremsen versehenen Vorder- 5: räder von Straßenfahrzeugen mittels übereinander angeordneter Blattfedern, -dadurch gekennzeichnet, daß' an den Enden eines vorderen, gegebenenfalls die Stoßstange tragenden Querträgers (2) des 6t Fahrgestells in an sich bekannter Weise je zwei schräg nach hinten und außen ragende viertelelliptische Federn (3) übereinander befestigt sind, deren Enden durch die die Achsschenkel (5) und die 6i damit verbundenen Bremsbacken tragenden Lenkzapfen (4) der Vorderräder verbunden sind.Individual suspension of the two steerable front wheels with brakes on road vehicles by means of leaf springs arranged one above the other, characterized in that two at the ends of a front cross member (2) of the 6t chassis, possibly carrying the bumper, in a manner known per se obliquely one above the other mounted rearwardly and outwardly projecting quarter elliptic springs (3), the ends through which the stub axle (5) and the 6 i associated brake shoes carrying the steering pin (4) of the front wheels are connected.
